Toolsets Module

This module provides a flexible system for defining and managing tool aliases/toolsets.
Toolsets allow you to group tools together for specific scenarios and can be composed
from individual tools or other toolsets.

Features:
- Define custom toolsets with specific tools
- Compose toolsets from other toolsets
- Built-in common toolsets for typical use cases
- Easy extension for new toolsets
- Support for dynamic toolset resolution

Usage:
    from toolsets import get_toolset, resolve_toolset, get_all_toolsets
    
    # Get tools for a specific toolset
    tools = get_toolset("research")
    
    # Resolve a toolset to get all tool names (including from composed toolsets)
    all_tools = resolve_toolset("full_stack")
